Scientists are developing a new strategy to defend Earth against powerful solar storms, proposing a system that could help protect satellites, power grids, and communications networks from catastrophic geomagnetic disruption.
The research, highlighted by Fox Weather, focuses on predicting and mitigating the impact of coronal mass ejections (CMEs) — massive bursts of charged particles from the Sun that can slam into Earth’s magnetic field, potentially causing fires and electrical overloads.
The proposed method involves using advanced space‑weather monitoring and early‑warning systems to detect incoming solar storms sooner and with greater accuracy. Researchers say improved forecasting could give operators of electrical grids and satellite networks crucial time to shut down vulnerable systems or switch them into protective modes.
The effort comes as scientists warn that Earth is entering a period of heightened solar activity. A major CME could cause widespread blackouts, disable GPS and radio communications, and damage satellites — with global economic losses potentially reaching trillions of dollars.
The new defence concept is part of a broader push by space‑weather experts to strengthen planetary resilience as solar storms grow more frequent and intense.
All electronic communication on Earth could be wiped out
As CTIF News reported in 2025, authorities around the world, and some fire services as well, are starting to prepare for the possibility of a catastrophic strength solar storm, and / or a geomagnetic storm similar to the Carrington Event of 1859, when telegraph lines melted and telegraph stations caught fire from the intense solar radiation.
At ESA's mission control in Darmstadt, teams faced a scenario unlike any before: a solar storm of extreme magnitude. Fortunately, this nightmare unfolded not in reality, but as part of the simulation campaign for Sentinel-1D, pushing the boundaries of spacecraft operations and space weather preparedness.
Before every ESA launch, mission teams undergo a rigorous simulation phase which rehearses the first moments of a satellite in space, while preparing mission control for any anomaly. Since mid-September, teams at ESA's European Space Operations Center (ESOC), in Darmstadt, Germany, have been immersed in simulations for Sentinel-1D, scheduled for launch on 4 November 2025.
To model one of the most extreme scenarios, simulation officers drew inspiration from the infamous Carrington event of 1859, the strongest geomagnetic storm ever recorded. The exercise replicated the effects of a catastrophic solar storm on satellite operations to test the team's ability to respond without satellite navigation and under severe electronic disruption.
"Should such an event occur, there are no good solutions. The goal would be to keep the satellite safe and limit the damage as much as possible," says Thomas Ormston, Deputy Spacecraft Operations Manager for Sentinel-1D.
This campaign included a rare activation by ESA's Space Weather Office of its Space Safety Center, inaugurated in 2022 as part of ESA's growing commitment to space safety. ESA's Space Debris Office and the spacecraft operation managers of other ESA Earth-orbiting missions also joined the exercise to enhance realism, simulating cross-mission impacts and coordination".
